There is a strong demand for more compact structure of axial flow pump. But the deterioration of efficiency and cavitation performance is inevitable. Therefore contra-rotating axial flow pump attracts attention from pump designers and engineers. Although the previous experimental results implied the advantages of contra-rotating axial flow pump and the importance of rear rotor design, the guideline of design was not found because of the complexity of internal flow. So the numerical analysis was performed to research the effect of rear rotor design to the performance. Rear rotor design parameters solidity, blade profile and stagger angle were changed and the optimum design of rear rotor are considered from numerical analysis results.
